This is my first post here but I do read a lot of everyone else's.  I am in the early stages of putting together an FE the will go into my restored 66 F100 Long Box.  Before I forget to tell you it will be bolted up to a top loader.  A 3 speed first and then as money becomes available it will be a 4 speed.    I am going for a street and highway driven truck - no drag racing - but I do have a lead foot and enjoy as much HP as I can get.  Won't be a daily driver but more like once a week to and from work which is 13 miles one way. Out here in the country we have long straight roads. I would like to see 400 horses but would not be the end of the world with 375. Really need it to run on pump gas.  Here is what I have accumulated to build with but I would love for anyone to step in with suggestions or comments.  At this time I have about $2,500 to play with.  Thanks guys - Mitch

BLOCK SPECIAL HIGH NICKLE X CASTING (I'm told)
Fresh Bored at 30 over.
Casting (8K29) Nov. 29 1968 Date Code by Oil Filter Bolt Up
Oil Pressure Relief cast (but not drilled) behind flywheel on left side (Not sure what this is even for)
Normal Meaningless Casting numbers 60 352 66 427 and Mold #25 DIF
Raised X Centered RS Lifter Galley between two center cylinders

HEADS

These are going to machine shop tomorrow for porting and bigger 2.09 and 1.65 valves installed

PISTONS
Have not purchased yet.

CRANK
Stamped with 20 (I assume is a 2U 390 crank) 1 3/8 Pulley Snout
I am not set in stone with this crank.  I really need to check the stroke to see exactly what it is. I purchased this as a running engine and it had 410 pistons in it before the tear down but that was 4 years ago.  I have slept since then and forgotten some things.

INTAKE MANIFOLDS (Have both)
Cast C6AE 9425G 180 degree Dual Plane
Aluminum Edelbrock Performer 390

RODS
C7AEB (Short - 6.488) 762-784 Grams

CAM
Crane 343941
Hydraulic Flat Tappet, Advertised Duration 272/284, Lift .533/.563
Basic Operating RPM Range: 2,000-5,000
Intake Duration at 050 inch Lift: 216
Exhaust Duration at 050 inch Lift: 228
Duration at 050 inch Lift: 216 int./228 exh.

Specific questions.
The Edel intake has much smaller ports than the heads.  I can see a flow problem here.
The heads need porting attention mostly to the exhaust ports?  Is that correct?
Is this block really a high nickle casting and something special?

I think you can view block images here.
